Notes
At the Peachtree Ridge HS track doing 2wu+12(400@10kw200r)+2cd, but messed up the repeats on the 310xt, so that only 5 are shown.
T+DP was 159, so slowdown factor was 1.057. From 8:44 that gives 9:13. On Garmin Connect I also have the 920xt data as well as this 310xt data, but since the intervals didn't start and end at the same time the data still doesn't appear right. I should have been able to do them all ok.
